Product Info

The Pioneer 4-Channel Car Amplifier 520W GM-A4704 is a 4-channel amplifier that powers front and rear speakers for improved in-car audio quality. It delivers 40W RMS per channel into 4Ω or 65W RMS per channel into 2Ω, with a 520W peak power rating for extra headroom during demanding passages. The amplifier is bridgeable, allowing the four channels to combine into two for driving a subwoofer or additional speakers with more power per channel.

A variable high-pass filter lets you fine-tune the frequency range sent to each speaker, while gain adjustment of up to 6.5V helps match the amplifier's output to your head unit for a cleaner signal. Automatic signal sensing turns the amplifier on and off with the audio source, removing the need for a separate remote turn-on wire. Speaker level inputs allow connection to factory wiring without a dedicated pre-amp output, and the one-body heat sink design manages heat across a compact chassis.
